How to choose a voltage stabilizer?

When choosing a stabilizer, you should pay attention to the following points:

1. First you need to determine the number of phases. To do this, it is necessary to calculate the total and peak power of the devices. In this case, it is worth adding an additional 30%.
2. Device stabilization range. If the voltage is constantly high, then you should choose the relay type. To protect all equipment - main type, and for a separate device - network type.
3. Experts recommend choosing high-precision stabilizers. They can be placed in a closet or on a shelf.
4. Power. When choosing power, it is also necessary to take into account that at low input voltage, the output power of the stabilizer becomes less.

When choosing a stabilizer, the main attention should be paid to its type. Type can be:

1. relay view: This is a transformer equipped with multiple input or output winding taps. Communication takes place through a power relay. If the input voltage is normal, then the device does not increase or decrease the voltage. If the voltage goes beyond the set limits, then the device turns on the relay and makes the device step down or step up the voltage. The main advantages of these types of stabilizers are low cost, high overload capacity, and short switching time. Among the disadvantages of this type, it is worth noting: stepwise regulation, noise during operation and wear of the relay contacts.
2. Electromechanical: this view represents a toroidal transformer. A current collector moves above the outer winding. When the voltage exceeds the set parameters, the servo moves the current collector, normalizing the output. Of the advantages of this type, it is worth noting the high overload capacity, smooth adjustment, adjustment accuracy. Among the shortcomings are noted: a long switching time, the current collector wears out over time, the high cost of the device.
3. inverter type: made on the basis of an inverter. Initially, the current is rectified, and then converted into alternating current due to the inverter. This results in a high adjustment precision. Among the disadvantages of this type stand out: low overload capacity and high sensitivity.

By the number of phases, stabilizers can be:

1. single phase: they are used in single-phase network houses to maintain a voltage of 220 V. They are used to connect household appliances and office equipment.
2. Three-phase stabilizers: they are used in residential and industrial premises in which there is a network of 380 V.

According to the type of connection, stabilizers can be:

1. Trunk: they are installed in the network and adjust the voltage of all electrical appliances, including lighting.
2. Network Stabilizers: they are plugged into an outlet. On the body they have one or more sockets to connect electromechanical devices.
3. Power (performance): power can be from 0.5 to 100 kW. It is important that the power of the stabilizer matches the power of the device.
